VALVE-RESEATING TOOL.

Application filed May 11,

My invention relates to valve reseating tools.

The object of my invention is to provide a valve reseating tool of this general character by which the seats of faucets, valves and the like can be accurately resurfaced, trued and renewed, so that washers will seat properly. The parts are adjustable and reversible. The centering element being constructed to fitover or into the different sizes of valve openings into which the valve trimmings are mounted when the valve is in use.

In the accompanying drawings forming a part of this specification and in which l1ke numerals designate like parts throughout the same I Figure l is a sectional view of the tool, showing same appliedto a faucet, and showing parts broken away to show its lnterior construction. 1

Figure 2 is a side view.

Figure 3 is a sectional view of the tool showing the centering element reversed on the feeding device, adapted to faucets of this type, a portion broken away to show the threads on the interior of the valve opening,

Figure 4 is a cross section of the tool-stem shown in Figure 1 on the line A-A.

F igureo is across section of the tool-stem shown in Figure 2 on the line B-B.

Figure 6 is a cross section of the tool-stem shown in Figure 3 onthe line C 0.

Figure 7 is a side view of the tool'stem clamping means.

Figure 8 is a side view of the feeding device.

Figure 9 is a bottom view of the cutter shown on the tool-stem in Figure 1.

Figure 10 is a bottom view of the cutter shown on the tool-stem in Figure 2. The parts may be identified by reference numerals with which they are designated upon the drawings, and are characterized individually as now set forth.

The faucet. 1 shown in Figure 1 shows the standard construction in which the seat of the faucet 2 is an integral part of the body. The faucet or valve seat may have a flat face as shown adapting it to flat washers, or a conical face adapting it to a conical washer, (not shown but understood in the art.)

3 an; opening in the valve body into which the valve trimmings are mounted when the valve is in use, the valve body maybe provided with outside threads at 4, or inside 1927.. Serial No. 196,550.

threadsv as at 4 adapted to take the valve cap, (valve cap not shown but understood in the art.) 2

The rotating means 5 is secured to the toolstem at its upper end. The tool-stem 6 is provided with, a longitudinal groove 7, adapted to engage means 17. is provided with a reduced integralsection 8, threaded to engage the threaded bore 11 in the cutter 9. The cutter may have a flat face as shown in Figure 1, or a conical face asshown in Figure 2 designated 9 The cutter is provided with a plurality of cutting edges as shown in Figure 9 at 10 :10,

or as 10'-10- in Figure 10.

the end of the locking The lower end of the tool-stein ,The centering element 26 is of conical configuration p'rovidedwith external threads 27, and internal threads 28, and an internalstop face 29, and. an externalstop face 30, and axial threaded bore 31.

The feeding device 18 having formed integrally therewith at itsupper end a socket 20, and a socket wall 21, and provided with an axial smooth bore 121:0 engage the toolstem, and also provided with a threaded exterior 19, adapted to engage .the axial threaded bore 31 in thecentering element. The lock ring 24; is internally screw-threaded registering with the threaded exterior of the feeding device, the flat face 25 of which coacts with the stop face 3O, when the tool is used as shownin F gure- 1, and the stop face 29 when the tool is used as shown in Figure The lock ring is adapted to lock the feeding device against movement in the centering element.

The clamping means 13 has an integral reduced portion 15, intermediate this portion an annular groove 16, and an axial smooth aperture 1.2 to engage the tool-stem, a threaded bore 14 at right angles to the axial smooth aperture is adapted to secure the locking means 17 The clamping means is rotatably mounted in the socketof the feeding device, andsecured therein by the terminal ends of the securing pins 23: that pass through the perforations 22: 22 in the socket wall 21. These pins have a tight fit in the socket wall, but a loose fit in the annular groove so. as not to interfere with the independent rotation of the tool-stem clamping means in the socket, or the independent rotation of" the feeding device on the clamping means. .The tool-stem 6 is round The tool-stem 6 l asa flat face'as shown at 32 in Figures 3 and (3, adapted to accommtulate the end of the toohstem locking means.

The tool-stem being mounted in the toolstem clamping means and feeding: device, is .slidahlv mounted in the clamping means when the grooved or llat sided tool-stem is used. and ii-t slidahly and rotatably mounted when the round tool-.stem used. and is slidahly and rotatably mounted in the feeding device in all cases. It therefore evident, that when the reseating tool is secured to the faucet to he reseated and the cutter is brought. in contact with the valve seat and locked in the clamping meane. the tool-stem with its cutter can he carried up and down by turning the feeding device.

The tool-Ftem can be operated entlv by the locking means alone. sary downward pressure being: manually applied to the rotating meana. on the upper end of the tool-stem in the. renewing movements, by simply alternating the loekii'ig and releasing ol the tool-stem as desired because the tool-stem being locked in the clamping means can not ride up from the valve seat, thus always giving :1 preferably true valve seat. irrespective of the lii eding method used in the combination.

The operation of the device is obvious.

The tool is secured to the faucet or valve. the cutter brought into contact with the valve seat. the tool-stem locked in the clanming device. the handle revolved, the teedint means is turned slightly downward thus pressure is applied to the cutter, the operation is repeated until desired results are obtained.

The construction of the. tool can be partly of steel and partly some other metal. or all of steel or some other metal. the construction itself can he made such as to attain the required strength without special reference to the materials used.

'hilc in the foregoing there has been illustratedin the drawing and dc erihed in the specification such combinations and arrangement of elements as constitute the preferred construction or embodiment of, this invention. it. is nevertheless desired to emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the auhjoined claims.
